Hi, These are links from a few meetings ago; I scribbled some notes afterwards but didn't have time to type them up and add the URLs. Some may still be useful to people, e.g. speeding up Python. Regular readers will see repetitions; I've a one-track mind.
Niklaus Wirth's programming language Modula-2, a descendant of Pascal, has co-routines. http://en.wikipedia.org/wiki/Modula_2 There's a Raspberry Pi "Bare metal" forum for those wanting to run code without an OS. http://www.raspberrypi.org/phpBB3/viewforum.php?f=72 The _Baking Pi_ articles from the University of Cambridge make a start on running some assembly on the OS-less Pi, though they cheat a bit and bring in some C to handle the USB stack. http://www.cl.cam.ac.uk/projects/raspberrypi/tutorials/os/ Design by Contact was favoured by Bertrand Meyer's Eiffel programming language. http://en.wikipedia.org/wiki/Eiffel_%28programming_language%29 Python's creator, Guido van Rossum, wrote Mondrian, a web application for code review, when at Google. He created another open-source version, Rietveld, that didn't depend on private Google technologies. It runs on App Engine and is used by the #golang developers. http://code.google.com/p/rietveld/ The slim "NAND" book, leads you through building a simple CPU from just NAND gates and flip-flops using Java simulators for a very simple hardware description language before having you write an assembler, virtual machine, and compiler for a simple Java-like language for it. It filled in the gap between TTL logic gates and assembler for me, i.e. how do CPUs work internally. http://www.amazon.co.uk/exec/obidos/ASIN/0262640686/ysk-21 http://www1.idc.ac.il/tecs/ Two-minute video of quadcopters balancing, throwing, and catching a pole. http://www.youtube.com/watch?v=pp89tTDxXuI The debugger gdb(1) supports symbols stored outside the executable and packaged by Debian, Ubuntu, etc., in separate *-dbg packages. http://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages SciPy, including NumPy, speed up maths with Python. Also Python, PyGame. http://www.scipy.org/ http://www.pygame.org/wiki/about Valgrind's author, Julian Seward, also wrote bzip2. _How to Shadow Every Byte of Memory Used by a Program_ explains how Memcheck, part of Valgrind, tracks every bit of memory's state. http://www.valgrind.org/docs/shadow-memory2007.pdf LLVM assembly code is being shipped for specialisation on the run-time platform, e.g. the OpenGL pipeline and LLVMpipe mentioned on http://en.wikipedia.org/wiki/LLVM Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2013-08-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
